METHOD AND SYSTEM FOR DATA DELIVERY AND REPRODUCTION
First Claim
1. A device, comprising:
- a computer-readable medium configured to store watermarked title data, the title data being watermarked with a code; and
a processor, configured to extract the code from the watermarked title data on the computer-readable medium, byreceiving watermarking information associated with the watermarked title data, the watermarking information identifying a plurality of placement locations and a number to frequency modulation relationship at each of the plurality of placement locations;
demodulating the watermarked title data at each of the plurality of placement locations based on the number to frequency modulation relationship; and
generating the code from the demodulated watermarked title data.

Abstract
Methods and apparatus for processing title data watermarked with a code. At least a portion of the title data may be watermarked at a plurality of locations within the title data with customer information data, so that the title data provided to a customer includes the watermark information. To obtain the code from the watermarked title data, watermarking information associated with the watermarked title data is first received. The watermarking information identifies a plurality of locations and a number to frequency modulation relationship at each of the locations. A different modulation scheme may be used at each location. The watermarked title data is demodulated at each of the plurality of placement locations based on the number to frequency modulation relationship. The code is then generated from the demodulated watermarked title data. A verification indication is output based in part on the generated code.

- 14. A computer-storage medium comprising title data that is watermarked with an identification code, the title data having at a plurality of locations the identification code modulated on the title data, with a different modulation scheme at each of the plurality of locations creating a random relationship between the identification code and modulation at each of the plurality of locations, and each of the plurality of locations being a random location within a group of available placement locations at which the title data has properties meeting at least one criterion.
